You can create a linked viewport by using a detail reference object. On the Object Info palette, choose the viewport that you want to link to. Then, the viewport will be permanently linked to the reference. If you move the viewport from one sheet to another, or change the number of the viewport, the reference will update automatically.

The concept is that you can create a reference object in your plans, sections, or elevations, and link this object to a viewport (maybe a detail) on a different sheet layer. When you update the number of the detail or move the detail from one sheet to another the drawing reference will update in the original plan, elevation, or section. You can link multiple reference objects to one viewport. That way, when you move or renumber the detail, all of your drawing references will update.

The most efficient way to create drawings is to use viewports. Viewports allow you to create as many plans, sections, elevations, and details on the same sheet. The viewports can be any scale, which allows you mix up the viewports on the sheet and have plans and details on the same page.

When you’re creating concept drawings, you can use the concept called sketch rendering. You not trying to trick your clients into thinking you drew the project by hand, you are trying to help them understand where the project is in the design process. Using sketch lines will take the focus off the details and put the focus back on the big issues.
